Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In view of the problem that tourists or tree flower fans cannot really experience the tree flower making process, the embodiment of the invention provides a Virtual Reality (VR) simulation method and device for tree flower making; the technology can be applied to the process that tourists experience and watch the tree flower through VR technology, and can also be applied to the process that a tree flower technician practices the tree flower skill through VR technology, and the technology can be realized by adopting related software or hardware, and is described by the embodiment below.
To facilitate understanding of the embodiment, a detailed description will be given to a VR simulation method for tree pruning disclosed in the embodiment of the present invention.
The first embodiment is as follows:
referring to fig. 1, a flow chart of a first VR simulation method for making a tree flower is shown; the method is executed by a server, and the server is respectively connected with a head-mounted display, a single-hand controller and a positioning base station; the positioning base station is respectively connected with the head-mounted display and the single-hand controller and is used for acquiring the position information of the head-mounted display and the single-hand controller; in practical implementation, the positioning base station may be integrated with the server, or may be separately disposed.
The method comprises the following steps:
step S102, generating an experience scene of tree flower digging; the experience scene at least comprises a wall body for reflecting the splashed molten iron;
in the experience scene of the tree flower simulated by adopting the VR technology, at least a wall body for spreading molten iron should be included, and preferably, the wall body can be simulated as an ancient city wall; the experience scene can also comprise a performance platform, a stage, other environment backgrounds and the like.
Step S104, acquiring the position relation between the user wearing the head-mounted display and a wall in an experience scene according to the position information of the head-mounted display;
step S106, acquiring the movement speed of the arm of the user according to the position information of the single-hand controller;
step S108, transmitting the position relation and the movement speed to a preset tree flower effect model, and outputting image data of the tree flower effect; wherein, the tree flower effect model is established according to the fluid dynamics principle;
step S110, the image data is played.
In the actual operation of the tree pruning, the position relation between the operator and the wall, the speed and direction of the arm swing of the operator and the like all influence the effect of the spark; therefore, when the VR technology is adopted to simulate the spark effect of the tree flower, the position relation between the user and the wall body and the movement speed of the user for swinging the arm need to be combined; the motion speed may be vector data, including speed magnitude and speed direction; the movement speed may be a set of data, including vector data of a plurality of movement speeds collected within a preset time period when the user swings an arm, so as to reflect a variation relationship of the movement speed of the user during the process of swinging the arm.
Because the molten iron belongs to the fluid and is pushed by the arm of a technician through the wooden spoon, the molten iron flies out of the wooden spoon, and the shape and the effect of sparks generated by the action on the wall body follow the fluid dynamics principle; the basic axiom of fluid dynamics is the conservation law, in particular conservation of mass, momentum and energy. The fluid is also assumed to obey the "continuity assumption". Fluids are composed of molecules that collide with each other and also with solids. However, the assumption of continuity considers that the fluid is continuous rather than discrete. Thus, properties such as density, pressure, temperature, and velocity are all considered to be well defined at infinitesimal points and to be continuously variable from one point to another. If the fluid is dense enough, it can be a continuum, the momentum equation of newtonian fluid is "navier-stokes equation", which is a nonlinear differential equation, and the stress describing the flow of fluid is linearly dependent on velocity and pressure. In addition to the mass, momentum, and energy conservation equations, there are thermodynamic equations of state that make pressure a function of other thermodynamic variables of the fluid.
The VR simulation method for tree pruning is executed by servers respectively connected with a head-mounted display, a single-hand controller and a positioning base station, and the position relation between a user wearing the head-mounted display and a wall in an experience scene can be acquired through the position information of the head-mounted display; the movement speed of the arm of the user can be obtained through the position information of the single-hand controller; the position relation and the movement speed are transmitted to a preset tree flower effect model, and image data of the tree flower effect can be output.

In the mode, the experience scene is more vivid through the experience scene obtained by processing the real tree flower shooting scene photo.
This step S202 can also be implemented by: drawing an experience scene schematic diagram of the tree flower by adopting 3D modeling software; rendering the experience scene schematic diagram to generate the VR experience scene with tree flowers.

In a three-dimensional experience scene, in order to obtain a more accurate position relationship between a user and a wall, the vertical distance between the user and the plane of the wall and the relative distance between the user and each edge of the wall need to be confirmed, and then the position of the user can be positioned at a point, so that a final spark effect is output according to the position relationship between the point and the plane of the wall.
Step S208, acquiring the arm swinging movement speed of the single-hand controller held by the user through a position sensing device arranged on the single-hand controller; the position sensing device can be a positioning module electrically connected with a positioning machine, and the arm swinging movement speed can be calculated and obtained by acquiring a plurality of position information of the arm and time information corresponding to the plurality of position information; it can be understood that a speed sensor can be directly arranged on the single-hand controller to directly acquire the arm swinging movement speed.
